FIX A COMPUTER THAT WON'T POWER ON

FIX A COMPUTER THAT WON'T POWER ON

PC not booting up or turning on? is the computer dead? well in this video we will go through some basic steps you can take to try and fix your computer. No computer problem is the same and to a non-tech savvy person fixing or repair a computer can be a bit daunting.

Just follow these basic steps and you should be able to diagnose your own computer problem. There are many reasons why a PC won't won't turn on but it you follow this video you should have a working computer or found a solution to the computer problem that you're having.

First off keep it simple and cheap.

1. Check for burning smell inside the computer or PSU (power supply) and check for any blown caps.
2. Do you have any spinning fans? or attempting to spin?
3. Do you have any lights on the motherboard? or any activity from the computer?
4. Check for any loose cables or components and make sure they are fully inserted. (make sure you are getting power to the motherboard.)
5. Try removing the CMOS battery for 30 mins and then put it back in. Or replace the CMOS battery with a new RC2032 battery. You can also remove the power cable and CMOS battery and hold the power button on to deplete the power from the computer. Hold for 30 seconds)
6. Check the power cable on another computer or better still if you have another cable try that on the dead computer. Replace if faulty.
7. Any beeping sounds coming from the computer?
8. Remove any unnecessary cable like CDROM drive and try and power on the computer.
9. Check the power button or bypass the power button on the PC case.
10. Check PSU with power supply test if you don't want to buy a new one right away. If you have a spare PSU use that for testing. Replace PSU if needed. (You can jumper the green and black wires with a paper clip to see if it powers on.)
11. Check ram sticks one at a time and see if it boots or turns on.
12. If you have a black screen and the computer is on it could be a GPU graphics card issue.
13. CPU or Motherboard issue. how do you which one it is? well unless you have a test bench setup with that socket motherboard to test the CPU you will never know. Most of the time it's the motherboard that's failed. But at this stage, you need to decide to buy or build a new computer or replace the motherboard to test the CPU. I know when you brought your £1500 or $2000 computer 8 years ago you think it's still worth that today but it's not worth £100 today. Time to make some decisions on what you want to do.

Remember testing a dead computer yourself can be a costly venture and a computer tech should have all the right tools and parts to save you money in the long run.

I am sure I have missed some bits out but it's hard to think of them when your filming.

Never would've thought it was the power cable being loose, thanks man

[navneetr]

Thank you!!! My power supply cables were loose from moving and you resolved my problem so quickly!

[deadmeme]

What the hell? A new power supply? I just bought one 2 months ago :(

**Spends hours troubleshooting. Finds out hours later that it was the PSU switch**

[ASpicyApple]

I spent about an hour on forums and none of them mention the cables from the power supply to my board. Fixed my pc in 4 minutes after finding this video!

[hazzewazeen]

Thanks a lot!
Thought my power supply was done, but checked the cable connectors and made sure all was tight and Boom, computer was back to life!
I owe you one. Keep up the good work! Atb/Hazze

[MichiFHK]

Thanks bud, you saved my day! The power button was broken, switched to the reset button as main power button worked like a charm! I owe you one!

[rayvoy]

i actually didnt know why my pc wasnt starting, then when you started talking about the power cord, i looked at my computer cord and it wasnt even plugged in my pc, so that helped a lot, otherwise i wouldnt have found it

[Lisdop]

Thanks! My brand new computer wouldn't turn on today, and this video helped me calm down and think straight. Turns out I unplugged the front panel when doing cable cleanup.

[GreaseTrapWiz]

Thank you! Thought I had to replace some parts but it was just the power switch like you showed!

[Tazurin]

Thank I never thought it was my power cable. And cried for an hour

[mousumimalakar]

Thanks man, because i never thought it would be a broken cable.

[taxikittens]

hey thanks for this! just built a new pc, first time, was about to have an anxiety attack when i got no power on boot. but your simple suggestion of making sure the psu cables were in all the way was what fixed it. they really do need to be pushed hard.

[FrenemieVines]

Thank You!!!! My computer is back on because of this video!! I started with switching cables - that's what it was!! So grateful for you and this perfect video!! 😘

Thanks Brian :-D

One utterly daft problem that will stop a machine is the usb socket under a flap.
i've found them shorting v+5 to case, usually because of people walking past and catching a cable plugged in, it breaks the contact support tongue and the contacts are bent into the shell, it may not short out straight away.

I got caught out because i could not find the 5 volt short to ground in the computer, that's because it was not inside.
I did call it some names lol :-D

[rayzy]

You saved my life. The old loose cable trick. Thankyou so much.

[Slayton]

Thank you so much after spending a crap load on my gaming computer and only getting to use it for maybe a year and a half it stop powering on. I did everything I could thank of to fix it. after a few months i was mad as hell and almost kick it out the door. I watch your video and come to find out it was the on and off switch. Thanks for the video.

[jasonwarbird]

Nice vid! Don't mind this format at all!

[doomsquid]

thanks for video, ended up resolving my issue by pulling out the power cable to the right of the RAM on the motherboard, blowing a tiny bit of dust and popping it back in
